Patented Jan. 19, 1932 UNITED STATES PATENT. OFFICE rrnmr H. D. wmsoa,01* mm, car-mom DISPENSING DEVICE Application filed October 27, 1980.Serial No. 491,535,

A further object of the invention is to provide a dispensing device forthe purpose aforesaid which includes a squeezing element for engagementwith a collapsible container, such squeezing element including a pair ofrollers, one of which is movable in anarc concentric to an actuatingmember therefor into and out of operative position with respect to theother roller.

A further object of the invention is to provide a dispensing device forthe. purposeaforesaid which is extremely simple in its construction,being formed of relatively few parts, positive inoperation, andinexpensive to manufacture.

With the foregoing andother objects in view, the invention consists ofthe novel construction, combination and arrangement of parts ashereinafter more particularly described,-and as illustrated in theaccompany ing drawings wherein arev shown embodiments of the invention,but it is to be understood that the description and drawings are to betaken as illustrative and that the invention is intended to be limitedonly by the scope of the claims hereunto appended.

In the accompanying drawings in which like numerals are employed todesignate like parts throughout the several views:

Figure 1 is a longitudinal section through a dispensing device inaccordance with this invention.

Figure 2 is a fragmentary section taken at a point indicated by the line22 of. Figure 1'.

Figure 3 is a transverse section taken at a point indicated by the line33 of Figure 1..

Fi re 4 is an end elevation of the squeezing. e ement. Figure 5 is anend elevation of a modifie form of squeezing element.

Figure 6 is a plan of the squeezing element 66 illustrated in Figure 5.Referring to the drawings in detail, the numeral 1 indicates a housingpreferably of rectangular formation and provided at one end thereof witha removable end will' 2 in order that a collapsiblecontainersuch as 3may beinserted into the housing. The removable wall 2 is providedcentrally thereof with an opening for the projection of the neck '4 ofthe container therethrough, the wall 2 further being provided with aclamping means indicated conventionally at 5 for V clamping the neck inposition, and with a. closure cap 6 for engagement with the neck 4 toprevent-the removal of "the contents of 0 the container.

tending at right angles to the central portion 12. Formed with thecentral portion 12 and extending in parallel spaced relation thereto isa tongue 14 which extends into the channel 10. The tongue 14 is of lesswidth than the distance between the channel forming members 9 andisformed with a pair of oppositely extendingprojections 15 formaintaining the tongue 14 in position within the channel 10. Thesqueezing element '11 further includes a knurled roller 16.which isformed with or mounted on a shaft 17 journaledin the end portions 13 ofthe yoke-shaped plate.

The squeezing element 11 further includes a knurled roller 18 which ismounted on or formed with a shaft 19 slidably and rotatably extendinginto a pair of recesses 20 formed in the end portions 13 in concentricrelation to a drive shaft 21 journaled in the end portions 13. The driveshaft slidably extends through an elongated slot 23 extendinglongitudinally of the housing 1. I

The drive shaft 21 is provided at one end thereof with an operating knob22 having a knurled peripheral face. The drive shaft 21 is furtherprovided with a pair of spaced pinions 24 which are in constant meshwith a pair of spaced gears 25 on the shaft 19.

In the use of the dispensing device above described, the removable wall2 is removed and the housing 1 is positioned with its open end up whichcauses the squeezing element 11 to move by gravity toward the closed endof the housing. The container is then inserted into the housing andsecured in position by means of the wall 2. When it is desired to ejectthe contents of the container, the housing is inverted, which causes thesqueezing element to move by gravity into a position to bring therollers 18 and 16 into engagement with the container on opposite sidesof the latter, the shaft 19 automatically assuming the proper positionwith respect to the recesses 20. The drive shaft 21 is then rotated forthe purpose of rotating the roller 18, by means of which an inner endportion of the container is squeezed between the rollers 18 and 16. Whenit is desired to remove the empty container, the direction of the driveshaft is reversed to move the roller 18 out of engagement with thecontainer, thereby permitting the ready withdrawal of the latter throughthe open end of the housing.

In the form of squeezing element illustrated in Figures 5 and 6, the endportions 26 of the yoke-shaped plate have journaled therein the shaft 27of a roller 28 which is provided with a series of elongated teeth 29extending throughout the length of the roller. Having its shaft 30slidably and rotatably mounted within the arcuate recesses 31 of the endportions 26 is a roller 32 which is provided on its peripheral face witha series of elongated teeth 33 which are in permanent mesh with similarteeth 34 on a drive shaft 35. The recesses 31 are concentricallyarranged with respect to the shaft 35. In this form of squeezingelement, the entire roller 32 constitutes a gear which is driven from apinion co-extensive in length with the roller and forming an integralpart of the shaft 35. With such an arrangement for rotating the roller32, there are no pinions or gears which may work loose on their shafts,and owing to the length of the meshing teeth, there is no possibility ofthe same becoming broken or stripped.

It is thought that the many advantages of a dispensing device inaccordance with this invention will be readily apparent, and althoughthe device preferably will be constructed in accordance with theembodiments herein illustrated and describe-d, it is to be understoodthat changes in the size, shape and arrangement of parts may be resortedto, so long as such changes fall within the scope of the invention asdefined in the appended claims.

What I claim is 1. A dispensing device comprising, a housing forreceiving a collapsible contamer, and a squeezing element slidablymounted withln the housing, said squeezing element including a carrier,a pair of rollers for abutment with the container on opposite sidesthereof, and a drive shaft for one of said rollers, one of said rollersbeing rotatably supportedby the carrier, the other of said rollers beingrotatably supported by the carrier and further being slidably supportedthereby to provide for bodily movement of such roller in an arcconcentric to the drive shaft.

2. A dispensing device comprising, a housing for receiving a collapsiblecontainer, means within the housing to form a channel extendinglongitudinally thereof, and a squeezing element slidably connected w thsaid channel forming means, said squeezing element including a carrier,a pair of rollers for abutment with the container on opposite sidesthereof, and a drive shaft for rotating one of said rollers, said rollerrotated by the drive shaft being supported by the carrier to provide forrotating movement of the roller and further to provide for bodilysliding movement thereof in an arc concentrlc to the drive shaft, theother of said rollers being rotatably supported by the carrier.
